ZEPHYR FATAL ERROR 3 in Bluetooth Mesh node

Hi 

There are four mesh nodes, so three of them send a lot of messages, and one receives all three node messages and also sends a few messages.

this error occurs in the node that is receiving messages:

ASSERTION FAIL [err == 0] @ WEST_TOPDIR/zephyr/subsys/bluetooth/host/hci_core.c:305
        k_sem_take failed with err -11

here are the mesh configuration parameters
CONFIG_BT_MESH_CRPL=128
CONFIG_BT_MESH_MSG_CACHE_SIZE=128
CONFIG_BT_MESH_ADV_BUF_COUNT=128
CONFIG_BT_MESH_SEG_BUFS=256
CONFIG_BT_MESH_RX_SEG_MAX=10
CONFIG_BT_MESH_TX_SEG_MAX=10
CONFIG_BT_MESH_RX_SEG_MSG_COUNT=10
CONFIG_BT_MESH_TX_SEG_MSG_COUNT=10
CONFIG_BT_MESH_LOOPBACK_BUFS=32

Thanks
